I think, @Perzival12 that may be your problem. Maybe reinstall PureOS from latest, try to upgrade, or try another distro, then we can see.

I don't mean the flatpak from flathub that'll be up-to-date, but the installed version of the flatpak software (the software you install to run flatpaks) may be out of date or the system drivers may be

Again, a single distro may pitch in, but they're dealing with things like Pipewire, Xorg, Wayland, Mesa, a desktop environment, and much more they don't really have time to dedicate someone to help update a little old game, and the distros that are based on stability (like debian stable) won't even consider it because it's not their goal. I was gonna suggest that... It is kinda mean, but there is such a thing as a not very good Linux distro, by virtue that it's not really updated. he does, but he gets errors when using it. I wonder if it's because of how old PureOS's flatpak probably is.

I'm a little confused what you mean by "projects like this" Also, Linux isn't a single entity, so I don't know what they on a whole would do. And sometimes some lesser known distros take longer with updates.

That would be something to contact PureOS about. You could open a bug tracker here: https://tracker.pureos.net/ and see what they say, though it seems pretty inactive. They'd have to implement a patch of some kind or get Debian to update the 0 A.D. version in testing (which is what I think PureOS pulls from)

I don't have any problem running the scenario editor, if you have a github please open an issue on the flatpak 0 A.D. ref, and we'll see what we can do.

I would say @Vantha's PR for campaign UI would have to be merged so we could have some form of narrative, then if the mod author is willing this may be a good first campaign to work on polishing.

Ok, that is pretty cool, maybe we'll get another release soon so everyone can play with it easily?

Wait, Germans are added? Sorry, I'm out of the loop. It would say that's a good idea.

I'm sorry, but known by whom? It's the first time I've heard of it. (Other than the problem with VMs)

What's your flatpak version?

So I take it's an intel or AMD?

I've had this error when I've launched 0 A.D. with a flatpak on fedora @Perzival12 what distro are you using and what graphic card do you have and how is the drivers installer?

The flatpak should have had the update for a while. Maybe try flatpak update in your terminal if the software center is acting strange.
